GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 280,379, dated July 3, 1883.

Application filed May 17, 1880. (Model.)

To all whom it may concern:

Be it known that I, SAMUEL A. JONES, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented new and useful Improvements in Grain-Binders, of which the following is .a full description, reference being had to the accompanying drawings, in which Figure 1 is an end elevation; Fig. 2, a side elevation; Fig. 3, a top or plan view; Figs. 4, 5, and 6, details of the cord cutter and holder; Fig. 7, a detail of the cord-carrying arm; Fig. 8, an elevationof the loop-holder and knot-tying devices; Fig. 9,-a vertical longitudinal section of the same; Fig. 10, an elevation of the forward end; Fig. 11, a detail of the stopwheel and its pinion"; Figs. 12, 13, and 14, details of the jaws or clamps; Fig. 15, a detail showing the style of knot made, the parts not being drawn tight.

This invention relates to that class of grain-- binders in which the cord is gripped by a rotary spindle and the knot tied by devices adapted to such purpose.

The improvement consists in the features of construction and combination hereinafter described and claimed, and illustrated in 'the drawings.

The spindle, comprising the two parts AA, is of sufiicient diameter to form the'knotdoop in the cord when wound around its projecting end, through which loop the ends of the cord are drawn. This spindle is located in asleeve or bearing, B B, and has an intermittent revolving movement with such sleeve or hearing, and, iri addition thereto, an independent sliding movement, by which its projecting or working end a can be drawn Wholly withinthe sleeve or projected outtherefrom, as required. The section A of this spindle has an independent reciprocating movement given to it for the purpose of producingan opening-between the shoulders at to receive the cord. The projecting end ais made tapering to facilitate the slipping off of the knot when completed; and the shoulders at are cut on an incline to insure a firm hold 011 the cord when caught between them, a sufficient space being left be tween the head B and the shoulder on A,w,hen the spindle is projected, to allow the knot-loop to be formed thereon.

The sleeve B B has an opening through it to receive the spindle A A and form a bearing therefor, and is supported in suitable bearings on the supports or stands F. On this sleeve or bearing are located the heads or 001- 'by means of the pin or anti-friction roller 0 on the collar 0, which said pin or roller enters the cam-groove ccc of the wheel 0. When the pin 0 is in the straight portion 0 of the groove the collars remain stationary, when it enters and passes through the poltion 0 the collars recede slightly, and when it enters and passes through the V-shaped portion 0 the collars both recede and advance. These movements are for the purpose of operating the cord jaws or clamps.

The collar D, carrying the collar D, is secured to the sleeve B by means of the pins 12, which enter and play back and forth-in a slot, o, formed in the sleeve B. The collar D is also connected to the reciprocating portion A of the spindle by the pins 11, which pins actuate the independent section of the spindle. The collars are reciprocated by means of a pin or anti-friction roller, d, which enters the camgroove (1 d d of the wheel D. \Vhen the pin (1 is in the straight portion d of the groove thecollars remain stationary, when it enters and passes through the portion d the collars advance slightly, and when it enters and passes through the V-shaped portion d the collars both recede and advance. These movements are for the purpose of operating the knotspindle A A.

The cam-wheels C D are located on the shaft F at the proper points to bring their respective grooves into engagement with the pins or anti-friction rollers c d, and when adjusted to give the required movements to the sliding collars at the proper time they are firmly attached in position by means of set-- screws f or other suitable devices.

The shaft F is supported in suitable bearings on the standards F, and is to be driven from the main drive-wheel by chains, or in other suitable manner.

The wheel or diskE is located on the shaft F, and has a cogged segment, E, on its periphery, which engageswith a pinion, E, on the sleeve B, the length of the segment being just suflicient to cause the sleeve B to make one complete revolution before it is disengaged from the pinion.

On the pinion E. is a stop, 6, arranged to. engage the flange c on the face of the wheel E and prevent rotation of the sleeve after the segment has passed the pinion, which engage ment takes place while the cam-groove d is acting to recede and advance the spindle A A. The engagement of the cogged segment E and pinion E occurs while the point a is projected and the groove (1 is engaged with the pin d, and is for the purpose of winding the cord around the end of the spindle to form the knot-loop.

' The cam-wheel G is located on the shaft L, which'is supported in suitable bearings on the standards L, and is driven by means of the wheel K, which gears with the pinion K on the shaft F.

The cord cutter and holder is made'from the plates H H H, the plate H being stationary and the plates H H having an oscillating or swinging movement on the plate H, to which they are pivoted by the single pivot h. The upper end of the plate Hhas aV-shaped notch, h, into which the cord is carried by the cord arm. The upper end of the plate H has a cutter, h, in the form of a V, both edges of which are cutting-edges, so that "it will cut the cord in either direction as it is carried past the notch h. The upper end of the plate H has a circular head, between the sides of which and the sides of the notch h the cord willbe caught and firmly held. The oscillating plates H H are operated from the cam-wheel G by means of the pin secured in the lower ends of. both plates, and projecting beyond the face of the plate H a sufficient distance to enter the cam-groove g g, the pin passing through a curved slot, in the plate H, to allowthe plates H H to swing. When the pin 9 is in the straight portions of the cam-groove no movement is imparted to the plates H H;

but as the pin passes from each straight section of the groove into the inclined sections 9 the plates will be swung or oscillated.

The jaws or clamps I I are located on the head B in the cut-away portion 1). The jaw I has its main portion i made broad, so as to furnish a large bearing-surface,and it is pivoted at j to the face of the cutaway portion 1) of the head B. The outer edge or face of this jaw I, is straight, and its inner face or edge is curved to allow the jaw to swing or turn on its pivot in the cut-away portion I). The jaw I is pivoted at j to the broad face 2' of the jaw I, and its lower end, i, is curved. To this end is pivoted one end of the lever or link i, the other end of which is pivoted to the collar C, so that as the pin 0 enters and passes through the groove 0 the upper ends, j j, of the jaws will be brought together, and as the pin passes into and through the groove 0 the upper ends, j j, with the cord clamped therein, will be swung out and down, carryingthe cord to the position to be caught and held between the shoulders a in the spindle. A spring, 6,

is located between the shoulder on the head B and the portion i of the jaw I, to keep the jaws closed when the cord has been grasped.

Between the end pivots of the bar 41 is 10- 8o cated the curved slot 1), with which the pin 1) engages, which slot is so formed as to cause the bar 4; to perform its function of opening and closing the jaws, and is so located as to cause the jaws to grasp the cord when the cordarm has carried it over to the cutter and holder, and to release the ends when grasped by the shoulder a on the return movement of the jaws.

The cord-arm J is to be reciprocated in any 0 suitable manner, and is so located as to carry the cord through the jaws I I when open and into the notch h of bar H, where it is caught and heldby the plate H and severed by the cutter h, the end of the main cord being held 5 between the head 1/ and bar H, and passing back through the eye or opening 76 of the cord-arm, through the guide or tube 2, which is attached to the frameO just below the cord arm, to the cord-spool suitably located.

The section M of the compressor is pivoted 011 the shaft L, and has a concave opening adapted to receive one-half or nearly one-half of the bundle. t' is so located that its for ward end will be in line, or nearly so, with the center of the spindle, and has an oscillating movement in a vertical direction to an extent sufficient to drop the bundle when bound. It is raised by means of its arm M, which has a friction-roller, m, arranged to engage with the acting face m of the cam M, which cam is firmly attached to the shaft L, and is so located that the curved portion of its acting face m will engage the roller m and hold the compressor M while the bundle is being bound, and the depressed or straight portion m of its acting face will allow the compressor to be depressed when it leaves the curved portion and again raise the compressor before the roller passes onto the curved portion. This cam is so located as to hold the compressor up while the bundle is being bound, permits it to be depressed when the binding is finished to discharge the bundle, and raises it in time to receive the next bundle.

The compressor N has a form corresponding tothat of M, so that when the ends of the two are in contact the gavel will be compressed between them. It is located on the end of a bar, N, which bar, with the compressor, is at tached to a frame, N, which frame can be reciprocated to advance and retract the com t0 the-framework of the machine.

pressor. As shown, the frame has an upper rack, n, and a lower rack, n, with which a cogged segment (not shown in the drawings) located on a suitable wheel driven by the shaft 5 l? engages to advance and retract the frame. The engagement with the rack n advances and with the rack n retracts the frame: These racks are so located that the compressor will be advanced and held during the binding of 10 the bundle and retracted when the bundle is bound and is to be discharged by depressing the compressor M.

The frame N is supported on a suitable frame, 0, located on the support 0, attached On the frame 0 are guides 0' 0, in which the bar N slides, and which hold the bar in position.

Suitable guides 0 0, are provided on the upper end of this frame 0, in which the cordarm J slides back and forth, the arm being operated by a suitable lever orcrank attached to the pin 1) on this arm, and operated by suitable devices from the wheel which reciprocates the frame N, or in' any other suitable manner.

The shaft P is supported in suitable bearings on the standards P, and has at its end a sprocketwheel, Q, over which a chain, Q, passes for driving the shaft from the sprocket-wheel Q on the end of the shaft L.

The spring R is located around the sliding portion A of the spindle, between a collar, r,

attached to the end of the portion A, and a collar, r, on the end of the projecting portion of the spindle, A, and acts to return the sliding portion after the cord has beencarried between the shoulders a, and hold the ends firmly while they are being drawn through the knot-loop.

The ring or collar 0 is held from revolving by means of the bar T, secured to the standard F, or bearing thereon,'in which bar is a slot, 8, which receives a pin, 8, on the ring 0, and allows the collars G O to reciprocate, but prelar D is held from revolving by the bar T, se cured to the standards F, in which bar is a long slot, t, to receive the pin d on the ring, which prevents the rotation of the ring D, but allows it, with the collar D, to reciprocate.

Suitable collars, S U, are provided to prevent end-play of the sleeve B and the shaft F. The parts are so timed that when the arm'J has advanced and carried the binding-cord over the bundle, between the jaws or clamps I I, and over the cutter and holder the pin 0 will enter the groove 0 and through the link i close the jaws and tightly grasp the cord. When the cord has been grasped the cutter H will be operated, severing the cord for the bundle from the main cord, leaving its ends firmly grasped by the jaws I I, the holder H at the same time catching the endof the main cordand holding it, the cutter and holder being operated-by the passage of the pin 9 through the portion g of the cam groove vents rotation of the ring 0. h The ringor col-- on the wheel G, which passage occurs as the pin 0 leaves the portion 0 of the groove on the cam-wheel C. When the end of the main cord has been caught by the holder H, the arm J is receded by its operating mechanism, leaving the main cord stretched between its end and the cutter and holder H H H in proper position to receive the next bundle. Thebundle-cord is left around the bundle, with its ends caught by the jaws or clamps I I, which are held tightly closed by the action. of thespring 17 or other suitable device. As the pin g leaves theincline g the 'cogged segment E" on the wheel Ewill engage the pinion E on the sleeve B and cause the latter to make one complete revolution, winding the portion of the binding-cord between the bundleand the jaws I I once around the projecting end a of the spindle next to the head B, thus forming the knot-loop. The engagement of the stop e and flange e prevents more than a single complete revolution, the engagement occur ring when the revolution. is completed. During the revolution of the sleeve B B and spindle A A the pins 0 d will travel in the straight portions 0 d" of the cam-grooves in the wheels 0 D and no reciprocating movements of the collars O D will be made. The pin 9 at the same time travels in one of the straight portions, 9, of the cam-groove on the wheel G. As the revolution of the sleeve B B and the spindle A A ceasesf the pine enters the portion 0 of the cam-groove on the wheel 0, and through the action of one side of such V- shaped groove advances the collars G O, causing the arm 1' to turn the ends j j of the jawsI I outward and downward, carrying with them the ends of the cord which they clamp.-

At the same time the pin (Z will enter and pass through the inclined portion (1 and short straight portion immediately following of the ca'nrgroove onthe wheel D, advancing the collars D D and the portion A of the spindle, thus forming an opening between the shoulders a a, into which the cord is carried by the outward and downwardmovement of the jaws. As soon as the cord is received therein the opening is closed by the action of the spring R, which recedes the section A as the pin d leaves the incline d, and the cord ends are caught and held between the shoulders. As the cord ends are caught by the shoulders a a the jaws I I are raised through the action of the arm i and the receding movement of the collars G 0, caused by the engagement of the pin 0 with the opposite side of the V-shaped portion 0 of the cam-groove in'the wheel 0. At the same time the spindle A A is receded, withdrawing the point a into the head B by the pin (1, which enters and passes through one side of the 'V-shaped portion d of the cam-groove in the wheel D, causing the collars D D to be receded. This receding movement of the spindle A-A withdraws the point a through the loop previously formed and draws theends of the cord through a such loop, thus forming a knot like that shown I in Fig. 15, except that the parts are drawn tight. As the pin (1 enters and passes through the opposite side of the V-shaped groove 01' the collars D D will be advanced, thus projecting the point a to its normal position to again receive a loop, and the bundle j ust bound will be discharged During this movement the compressor N will be receded by means of its actuating devices. The compressor M will be permitted to fall to discharge the bundle and then raised to bring it into position to receive the next bundle by the working-face m of the cam M acting on the arm M, the grain for the next bundle being deposited in the space between the compressors and above the binding-cord, so that the advance of the arm J, which is coincident, or nearly so, with that of the compressor N, will carry the cord over the head B and around the bundle, to be again caught and manipulated, as just de-' scribed.

The operation will be clearly understood from the foregoing description.

The divided spindle A A may be formed either round, square, or other suitable shape; and in order to prevent the cord from being carried in by the withdrawal of the point a, so as to interfere with the movements of the spindle, grooves w are formed in the point to receive projecting pins 10 on the head B, at the outer end, which pins serve as guards to prevent the drawing in of the bindingcord.

A spline or other suitable means can be used to lock the collars O C and D D to the sleeve B to allow a reciprocating movement.

\Vhat I claim as new, and desire to secure by Letters Patent, is
